Bob meets with Bart Cox and Dave Peck to explain how to create a storm-ready roofing system.
Clip Summary
Bart Cox of Hanson Roof Tile and Dave Peck of D. Peck Roofing explain the roof covering system to Bob as they tour the Punta Gorda storm-ready site. Cox explains how Hanson Roof Tile has improved their design and now manufactures extruded cement barrel tiles at four plants in Florida. The tiles are made of cement, sand, and pigment, and are extruded, cut, and pre-drilled for fasteners at the factory. Cox explains that tiles were once laid directly on top of the roof paper with no fastener or adhesive. In Florida, high winds later forced roofers to apply cement adhesive to the tiles. When fabrication shifted to a less-permeable cement product, the tiles no longer adhered to the cement. Now they are mechanically fastened into the roof decking through the pre-drilled holes. Dave Peck, who has been roofing for the past 15 years, explains a system that has evolved over the years in response to hurricanes, water, and wind damage. Their crews now mechanically attach the 30 pound felt paper, then hot mop each course of 90 pound roll roofing with asphalt and nail it in place along the upper edge of each course. At the final point of susceptibility, the hip or ridge line, the roofers now use a metal hip and ridge nailer board. The cap tiles are nailed to the board with additional foam adhesive underneath to keep them in place. Experience has taught the roofers that hip and ridge tiles must be firmly affixed to prevent blow-off and damge to field tiles and other property.
